Is 18-3(2p+4) -3p equivalent to 3(2-3p)

Murljashka [212]

Answer:

<u>Yes they are equivalent.</u>

Step-by-step explanation:

Use PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

Distribute or multiply -3 with 2p and 4 to get -6p and -12.

You will then have 18-6p-12-3p, simplify to get 6-9p

For the second equation multiply 3 with 2 and -3p, you will then get 6-9p as well.

They are equal, hope the helps ;)

. Here is an equation 2x + 9 = -15. Write three different equations that have the same solution as 2x + 9 = -15. Show or explain

Anettt [7]

Answer:

1. $x-3=-15$
2. $2x=-24$
3. $2x-3=-27$

Step-by-step explanation:

Given the following question:

$2x+9=-15$

To find three equations that have the same solution as the given equation we have to first solve the equation.

$2x+9=-15$
$9-9=0$
$-15-9=-24$
$2x=-24$
$2x\div2=x$
$-24\div2=-12$
$x=-12$

<u>Equation one:</u>
$x-3=-15$
$-3+3=0$
$-15+3=-12$
$x=-12$

<u>Equation two:
</u> $2x=-24$
$2x\div2=x$
$-24\div2=-12$
$x=-12$

<u>Equation three:</u>
$2x-3=-27$
$-3+3=0$
$-27+3=-24$
$-24\div2=-12$
$x=-12$

Hope this helps.

The dimensions of a rectangular garden were 4m by 5m. Each dimension was increased by the same amount the garden then had an are

pogonyaev

The dimension of new garden is 7 meter by 8 meter

<em><u>Solution:</u></em>

The dimensions of a rectangular garden were 4m by 5m

Length = 4 m

Width = 5 m

Each dimension was increased by the same amount the garden then had an area of 56 square meter

Let "x" be the amount of increase

Then,

Length = 4 + x

Width = 5 + x

Also, given that,

New area = 56 square meter

<em><u>The area of rectangle is given as:</u></em>

$Area = length \times width$

<em><u>Substituting the values we get,</u></em>

$56 = (4+x)(5+x)\\\\56 = 20 + 4x + 5x + x^2\\\\x^2 + 9x + 20 - 56 = 0\\\\x^2 + 9x -36=0$

<em><u>Let us solve the above equation by quadratic formula</u></em>

$\text {For a quadratic equation } a x^{2}+b x+c=0, \text { where } a \neq 0\\\\x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

<em><u>Using the above formula,</u></em>

$\text{For } x^2+9x-36 \text{ we get , }$

a = 1 and b = 9 and c = -36

<em><u>Substituting the values of a = 1 ; b = 9 ; c = -36 in above quadratic formula we get,</u></em>

$x = \frac{-9\pm \sqrt{9^2-4\cdot \:1\left(-36\right)}}{2\cdot \:1}\\\\x = \frac{-9\pm \sqrt{81+144}}{2}\\\\x = \frac{-9 \pm 15}{2}$

<em><u>We get two solutions,</u></em>

$x = \frac{-9+15}{2} \text{ or } x = \frac{-9-15}{2}\\\\x = 3 \text{ or } x = -12$

Since dimension cannot be negative, ignore x = -12

Thus solution is x = 3

Length = 4 + x = 4 + 3 = 7

Width = 5 + x = 5 + 3 = 8

Thus dimension of new garden is 7 meter by 8 meter

A person can do a job in 6 days. Another can do the same job in 4 days. If they work together, how long do they need to finish t

NeX [460]

Answer:

2.4 days

Step-by-step explanation:

Time working together,t ,is

1/t = 1/a+ 1/b where a and b is the times working alone

1/t = 1/4 + 1/6

Multiply each side by 12t to clear the fractions

12t( 1/t )= 12t(1/4 + 1/6)

12 = 3t+2t

12 = 5t

Divide by 5

12/5 = 5t/5

2 2/5 =t

2.4 days
